I have just tried (downloaded OS X version) but it results strangely empty with no transactions in the history, that is quite impossible. So maybe I made some mistakes. Any idea?
Did you extended your seed with custom word/s? If so, add that extra word.
If you did not add an additional word, search for the Bitcoin address that you deposited to. Remember where you purchased Bitcoin from and search for the ID for that transaction. After you get the address, search for that address in the address list or type in the console and type ismine("YOUR_BITCOIN_ADDRESS").
If that address is not in the wallet, you most likely made a mistake with the wallet seed.
